I'm not sure about this, but a scholarship is a one year commitment by both the player and the school. Once the letter of intent has been signed, both the school and the player are obligated to honor that commitment (hence scholarship) for one year.Coaching staff pulled his scholarship because they felt he wasn’t good enough based on his high school season
If both the player and the school agree it is in the best interest of both the player and the school, then by mutual agreement [assuming all conditions of the contract are still met] the school and player will no longer be required to honor the contract.
The coaching staff could not just decide they will not honor the contract made by the letter of intent if the player does not agree to it. The school and player are obligated to honor the contract unless it is mutually agreed to by both parties to cancel it.
If somebody with greater knowledge on this than I could comment, it would be appreciated.
